Crystal structure of (μ-hydrogen disulfato)-μ-oxido-bis[(4,4′-di-tert-butyl-2,2′-bipyridine)oxidovanadium(IV/V)] acetonitrile monosolvate

The dinuclear oxidovanadium(IV/V) complex, [V 2 (HS 2 O 8 )O 3 (C 18 H 24 N 2 ) 2 ]·CH 3 CN or [V 2 O 2 (μ-O)(μ-H(SO 4 ) 2 )(4,4′- t Bubpy) 2 ]·CH 3 CN (4,4′- t Bubpy = 4,4′-di- tert -butyl-2,2′-bipyridine), has crystallographic C 2 symmetry and exhibits a distorted octahedral geometry around the vanadium center, where the two 4,4′- t Bubpy ligands are nearly orthogonal to each other. The two vanadium ions are linked by an oxo anion and a unique protonated sulfate anion [H(SO 4 ) 2 3− ]. In the crystal, intermolecular C—H...π and π–π interactions between the 4,4′- t Bubpy ligands are present, leading to a three-dimensional network.
